Android - A mobile operating system run by Google Honeycomb - The codename for the latest version of Android Tablet - A touchscreen mobile computer that is usually one piece of hardware Widget - A small application that runs open in a small area of the screen
Earlier today, Google hosted an Android event officially showing off Honeycomb, and their online android market. They started off with Honeycomb news, and then went on to announce an online Android Market. Google Android's chief Andy Rubin introduced Hugo Barra, Android head of mobile products, to explain android 3.0, also known as Honeycomb. Tablet With Honeycomb Honeycomb was shown only on a tablet device, so we are yet to know much about how it would work on a phone. Honeycomb completely redesigns the Android interface. The status bar, which tells the time, battery life, connection info, and notifications, has been completely removed from the top of the screen, and replaced by a small black bar at the bottom of the screen. This bar slightly resembles the Windows taskbar. The bar tells a user the time, battery information, notifications, and connectivity info. It also includes a back button, a home button, and a multitasking button. When the multitasking button is tapped, a sidebar appears on the left side of the screen, showing you a visual list with all of the currently running apps. When one of the apps is tapped, it seamlessly opens up into full screen. 
Tablet with Andoid 2.2 Honeycomb also focuses a lot more on not having all your apps in a grid, as seen on the Apple iPhone, previous builds of Android, and many other mobile operating systems. In Honeycomb, a user will put a few important widgets on the homescreen, as well as icons for the few most used apps. The rest of the apps will be accessible through a small button near the upper right corner of the screen. Users also have multiple home screens which they can swipe through, each showing different widgets and app icons. Honeycomb also comes with a redesigned notification system. When a notification pops up, it won't be intrusive, it will lay at the bottom right corner of the screen, but will still show some information about the notification. Google also included the application bar in Honeycomb. The application bar is a small bar at the top of an application that includes commands for that program. Windows has know this for a long time, as many applications have small bars with commands such as file menu, edit, and more. Android's application bar's commands can also change based on what is happening right now in the app. For example, in an email app, you might get compose message, and some other commands. When you have a message selected, on the other hand, you might see, delete, mark as spam, and more. Google also focused on it's powerful graphics and animation capabilities. The demos Google showed were impressive, but something apple devices could do for a long time. Google spent half the time talking about Honeycomb, and the other half talking about it's new online app store, known as Android Marketplace. For a long time, one must be connected on his Android Device to download apps from the Marketplace. At today's event, Google announced it's Online App Store. Like Apple's online store, the online app store will allow you to download apps away from your computer, rather than have to buy them through the phone. The app store looks nice, and kind of resembles the app store for Google Chrome. 
Android Market Online Unfortunately, you cannot download the app on your PC, rather you can only discover them. The app store integrates sharing, and allows you to share an app on Twitter, but is lacking any Facebook integration. Overall, Honeycomb looks great, and the online Android store has been widely waited for, and is much more convenient. I'd like to see the ability to download to the PC and then syncing, and some more social integration, including Facebook.
